Abstract

A machine instruction is provided that has associated therewith an opcode to identify a perform pseudorandom number operation, and an operand to be used by the machine instruction. The machine instruction is executed, and execution includes obtaining a modifier indicator. Based on the modifier indicator having a first value, performing a deterministic pseudorandom number seed operation, which includes obtaining seed material based on information stored in the second operand. A selected hash technique and the seed material are used to provide one or more seed values, and the one or more seed values are stored in a parameter block.
